Left Atrial Strain Prediction of New-Onset Atrial Fibrillation in Apical Hypertrophic Cardiomyopathy with Cardiac MRI.
Cardiac MRI-derived LAS was independently associated with new-onset AF in AHCM and provided incremental prognostic value beyond routine clinical and left atrial volumetric measures and time-dependent ROC analyses demonstrated that LAS identified the development of AF well across prespecified time horizons.
